Hydraulic oil in crankcase on tc35d

[deerslayer1971]

we replaced the seal on the hydraulic pump then put it together it seemed fine went to use it after 15 minutes the crankcase was full again could something be building pressure and blowing the seal? Hydraulics sounded and worked normal

Did you replace both seals in the hydraulic pump or just the outer seal. If the pump blows out, it's most likely caused by the inner seal. The outer seal blowing is just a symptom of the real problem.
